Add check bison version in configure.ac file.
To build correctly matiec we need bison greater or equals than 2.4 version.
Now the "configure" script is able to check if system has correctly requirements.
#!/bin/bash
# assume no error to start with...
error=0
for ff in `ls *.test`
do
for id in `cat $ff | grep "^#" | sed "s/#[^ ]*//g"`
do
sed s/XXXX/$id/g $ff > $ff"_"$id.iec
if `../../../iec2iec $ff"_"$id.iec -I ../../../lib > $ff"_"$id.out 2>$ff"_"$id.err`
#if `../../../iec2c $ff"_"$id.iec -I ../../../lib > $ff"_"$id.out 2>$ff"_"$id.err`
# TODO before deciding test is success [OK]
# - test whether xxx.out has size <> 0
# - test whether xxx.err has size == 0
# - (?) test whether xxx.out2 is identical to xxx.out
# - (?) test whether xxx.err2 has size == 0
# - perhaps produce a [WARN] instead of [ERROR] in cases of (?)
then echo "[ O K ] " $ff "->" $id

then echo "FAILURE -> At least one of the tests failed!"
else echo "SUCCESS -> All tests passed!"
